两栖动物与其他变温脊椎动物共享皮外色素系统，由各种器官和组织中的含黑色素细胞组成。我们描述了三种无尾动物物种（Scinax similis、S. fuscovarius 和 S. fuscomarginatus）内脏色素沉着的种间变异。我们分析了每个物种的 15 名成年雄性在繁殖期的内脏色素沉着。对个体进行称重和测量，并在立体显微镜中对内脏色素细胞进行分类和记录。色素细胞的形状和数量因器官和物种而异。心肺系统、消化系统、泌尿生殖系统和腰骶腹膜检测到显着差异。在泌尿生殖系统中，主要差异出现在睾丸中，其中只有S. fuscomarginatus有不同程度的色素沉着。 Anat Rec，2012。(C) 2011 Wiley periodicals, Inc.
Amphibians share with other ectothermic vertebrates an extracutaneous pigmentary system consisting of melanin-containing cells in various organs and tissues. We describe the interspecific variation in the visceral pigmentation in three anuran species (Scinax similis, S. fuscovarius, and S. fuscomarginatus). We analyzed the visceral pigmentation of 15 adult males from each species during the reproductive period. The individuals were weighed and measured, and the pigmented visceral cells were classified and documented in stereomicroscope. The shape and amount of pigment cells differed among organs and also among species. Significant differences were detected in the cardiorespiratory system, digestory system, urogenital system, and lumbosacral peritoneum. In the urogenital system, the main difference was observed in the testes, in which only S. fuscomarginatus had varying degrees of pigmentation. Anat Rec, 2012. (C) 2011 Wiley Periodicals, Inc.
